The first python command above runs all tests related to tables,
mapping, creating, dropping, etc. The second one executes a single
test to generate SQL to create a trigger. The third runs all the
functional tests. Please review the pytest documentation for further options.

Environment Variables

By default, the tests use a PostgreSQL database named
pyrseas_testdb which is created if it doesn't already exist. The
tests are run as the logged in user, using the USER Unix/Linux
environment variable (or USERNAME under Windows). They access
PostgreSQL on the local host using the default port number (5432).

The following four environment variables can be used to change the
defaults described above:

PYRSEAS_TEST_DB

PYRSEAS_TEST_USER

PYRSEAS_TEST_HOST

PYRSEAS_TEST_USER

Restrictions

Unless the test database exists and the user running the tests has
access to it, the user role will need CREATEDB privilege.

Most tests do not require special privileges. However, tests that
define dynamically loaded functions (e.g.,
test_create_c_lang_function in test_function.py)
require SUPERUSER privilege. Such tests will be skipped if the user
lacks the privilege.

Most tests do not require installation of supporting PostgreSQL
packages. However, tests that define dynamically loaded functions
(see above) require that the contrib/spi module be
installed.

On Windows, it is necessary to install Perl in order to run some of
the tests. A suitable choice is Strawberry Perl which can be
downloaded from http://strawberryperl.com/releases.html. However, the
default installation is placed in C:\strawberry and can hold a
single Perl version. Furthermore, PostgreSQL 8.4 and 9.0 are linked
with Perl 5.10 whereas PostgreSQL 9.1 and 9.2 are linked with 5.14.
It is recommended that Perl 5.10 be installed as this gives the fewest
test failures. See this blog post
for more details.

The COLLATION tests, run under PostgreSQL 9.1 and 9.2, require the
fr_FR.utf8 locale (or French.France.1252 language on Windows)
to be installed.

Testing Checklist

The following is a summary list of steps needed to test Pyrseas on a
new machine. Refer to development for details on how to
accomplish a given installation task. "Package manager" refers to the
platform's package management system utility such as apt-get or
yum. Installation from PyPI can be done with either pip or
easy_install. Some operations require administrative or superuser
privileges, at either the operating system or PostgreSQL level.

Psycopg2, PyYAML and Tox all have to be installed twice,
i.e., once under Python 2.7 and another under 3.2.

On Windows, install Perl (see discussion above under
"Restrictions"). On Linux, usually Perl is already available.

As postgres user, using psql or pgAdmin, create a test user,
e.g., your name. The user running tests must have at a minimum
createdb privilege, in order to create the test database. To run
all the tests, the user also needs superuser privilege.

Create directories to hold tablespaces, e.g., /extra/pg/9.1/ts1
on Linux, C:\\extra\\pg\\9.1\\ts1 on Windows. The directories
need to be owned by the postgres user. This may be tricky on
older Windows versions, but the command cacls <dir> /E /G
postgres:F should suffice. Using psql or pgAdmin, create
tablespaces ts1 and ts2, e.g., CREATE TABLESPACE ts1
LOCATION '<directory>' (on Windows, you'll have to use, e.g.,
E'C:\\dir\\ts1', to specify the directory).

On Windows, for PostgreSQL 9.2, the default installation is owned
by the Network Service account, so the cacls command should
be cacls <dir> /E /G networkservices:F.

Note

The creation of users/roles and tablespaces has to be
repeated for each PostgreSQL version.

Install the locale fr_FR.utf8 on Linux/Unix or the language
French.France.1252 on Windows.

On Debian and derivatives, this can be done with the command:

sudo dpkg-reconfigure locales

On Windows, open the Control Panel, select Date, Time, Language,
and Regional Options, then Regional and Language Options (or Add
other languages), click on the Advanced tab in the dialog and
then choose “French (France)” from the dropdown. Finally, click
OK and respond to any subsequent prompts to install the locale,
including rebooting the machine.

Change to the Pyrseas source directory (created by the second step above).

Define the PYTHONPATH environment variable to the Pyrseas source
directory, e.g., on Linux, export PYTHONPATH=$PWD, on
Windows, set PYTHONPATH=%USERPROFILE%\somedir\Pyrseas.

Define the environment variables PG84_PORT, PG90_PORT,
PG91_PORT and PG92_PORT to point to the corresponding
PostgreSQL ports.

Invoke tox. This will create two virtualenvs in a .tox
subdirectory--one for Python 2.7 and another for 3.2, install
Pyrseas and its prerequisites (Psycopg2 and PyYAML) into each
virtualenv and run the unit tests for each combination of
PostgreSQL and Python.
